Wind Chill damage decreased by 20%and now increases damage taken by 5% per stack.

Classes: General

Dodge: Death Knights, paladins, and warriors no longer receive any bonus to their chance to dodge from Agility. Their base chance to dodge is now a fixed 5%.

Parry: Death Knights, paladins, and warriors now receive 27% of their Strength bonuses as parry rating, up from 25%. This conversion still only applies to Strength above and beyond their base Strength.

Pyroblast: The version of this spell cast when Hot Streak is not active did slightly less damage than the Hot Streak version. Its damage has been increased so that both versions of Pyroblast now do the same amount of damage.

Spellsteal mana cost has been increased 100%.

Fire

Impact: When Living Bomb is spread via this talent, it will only be spread to two additional targets. The net effect is that if the Mage’s most recent Living Bomb target is the same as their Impact target, that target will no longer lose the Living Bomb effect. If Living Bomb is active on multiple targets when the Impact effect is cast, Living Bomb will remain active on the most recent Living Bomb target, and will be added to two other nearby targets.

Frost

Deep Freeze and Ring of Frost will now cause diminishing returns for each other.

Seal of Righteousness – now can be proc’d by any melee ability, not just single target melee abilities. This adds Hammer of the Righteous (the physical component) and Divine Storm to the list of abilities that can proc it. In addition, Seal of Righteousness procs can now crit.

Holy

Walk in the Light now improves Word of Glory healing by 30% in addition to its current effects.

Restoration druid Tier 11 2-Piece: This set bonus has been redesigned to work with the new Restoration druid mastery. Druids with this bonus now receive the bonus to Spirit while the Harmony mastery bonus to periodic healing is active.

Tier 12 Set Bonuses

Hunter 4P: The effect which makes Shots cost no focus now also makes Kill Command cost no focus.

Mage 2P: This set bonus can now also be triggered by Frostfire Bolt.

Mage 4P: The portion of this bonus referring to Arcane Missiles have been removed. Instead, the set bonus now makes Arcane Power reduce the cost of Mage spells by 10% instead of increasing their cost.

well looks like a lot of people were STILL too dumb to beat the bosses
and since there's no new tier content anywhere close they try to make it more easy (and therefore more interesting) for twinks and dumb people.
awesome.

I know they always nerf old content when new comes out but this is just over the top, sad to see Blizzard catering to all crybabies, this is coming from someone who haven't even cleared the content yet. Biggest nerf to content I've seen since 3.0.

Seal of Righteousness – now can be proc’d by any melee ability, not just single target melee abilities. This adds Hammer of the Righteous (the physical component) and Divine Storm to the list of abilities that can proc it. In addition, Seal of Righteousness procs can now crit.
